Cons

The Sony SRS-Z50 is a computer speaker available either by itself or in a pair. As a more affordable downgrade from the SRS-Z100, the SRS-Z50 speakers lack an integrated amplifier unit and therefore output only 5W. Like its peer however, the magnetically shielded Z50 speakers are lightweight and portable, making them especially useful for on-the-go users who rely on a notebook or other portable music device. Despite its weak power output, it does host a Mega Boost function that allows it to deliver slightly louder/more booming audio, although it still lacks tremendously versus its predecessor.
